  • Detection of protein interactions
    Publication number: 20020094519
    Abstract: The present invention provides methods for determining the sequence of nucleic acids encoding interacting polypeptide sequences. Two hybrid assays are carried out to select host cells containing nucleotide sequences encoding interacting proteins. The identity of the nucleotide sequences is determined by isolating the nucleotide sequences from the selected host cells and carrying out sequencing reactions on the nucleotide sequences.
